How to Generate a QR Code for Free (Any Type)

Por ToolHub TeamMay 28, 2026

QR codes are everywhere — menus, business cards, packaging, and marketing materials. Creating one is free and takes less than a minute.

Types of QR Codes You Can Create

  • URL QR Code: links to any website or page. The most common use case.
  • WiFi QR Code: lets guests connect to WiFi by scanning — no typing passwords.
  • Contact Card (vCard): shares your full contact information; scan to save to phone contacts.
  • Email QR Code: opens an email app with a pre-filled address.
  • Phone Number: opens the dialer with the number pre-filled.
  • Plain Text: any text message up to a few hundred characters.

How to Create a QR Code on ToolHub

Step 1: Open the QR Code Generator. Visit toolhubpro.co/tools/qr-code-generator.

Step 2: Select QR type. Choose URL, WiFi, Contact, Email, etc.

Step 3: Enter your information. Fill in the required fields for your type.

Step 4: Customize appearance (optional). Change foreground and background colors, add your logo in the center, and adjust size and error correction.

Step 5: Download. Save as PNG (for digital use) or SVG (for print materials).

QR Code Best Practices

  • Error correction level: use "H" (30%) when adding a logo, and "M" (15%) for standard QR codes.
  • Minimum size: print at least 2cm x 2cm (0.8 inches). Smaller QR codes may not scan reliably.
  • Contrast: dark on light works best. Avoid low-contrast color combinations.
  • Testing: always test your QR code before printing, with multiple phone models.
